Well Driller Licensing Requirements and Eligibility

Domain 1 covers the legal authority to drill a well in Ohio and the qualifications an applicant must document. The exam tests licensing statutes and rules, not drilling mechanics.

Who may drill

Ohio Revised Code Chapter 1521 requires a license from the Chief of the ODNR Division of Water Resources (DWR) before a person engages in well drilling. Local health districts issue permits for private water systems, but a local permit does not substitute for the state driller license.

Eligibility file

  • Be at least 18 and submit a complete DWR application with fee.
  • Document supervised experience under a licensed driller; the required duration depends on the license class and must be verifiable.
  • Pass the DWR written examination covering construction, grouting, abandonment, law, and reporting.
  • Provide the required financial assurance/bond and disclose any enforcement history.
  • Maintain continuing education and renew before expiration; notify DWR of address or employment changes.

Worked example

An applicant has drilled for one year as a helper and holds a local contractor's license. That is not enough: the local license is irrelevant to state well-driller licensure, and one year may not satisfy the supervised-experience requirement. The applicant must accumulate documented experience under a licensed driller, apply to DWR, and pass the examination.

Traps

Do not assume that a pump-installer credential authorizes drilling; the license classes are separate. Do not let a license lapse while still drilling, and do not count undocumented on-the-job time.
